Here, we will list three signal transform properties that we will use later in the study of OTFS. A comprehensive overview of signal transform properties can be found in [1]}. Let \(x\) , \(y\) , and \(z\)  are sequences with same periods and let \(Z_x\) , \(Z_y\) , and \(Z_z\)  be there DZTs. Then following properties hold:
